Я вчера спрашивал там о OpenCV4Tegra не поддерживает GPU ответ был таков: "Opencv в jetpack давно отключил gpu"
Jetson tx2 не использует GPU для opencv_dnn?
Я запустил код с тремя версиями OpenCV:
1-ros-kinetic-opencv3 ......... CPU
2- OpenCV4Tegra. ................ Процессор согласно вчерашнему ответу.
3 - OpenCV с GPU, я собрал его из исходного кода, все в порядке, но все версии оченьочень медленный, и между ними нет заметной разницы. число кадров в секунду примерно 3–4,6

Я купил Jetson для получения высокого кадра в секунду.
Поверьте мне, что компьютер работает быстрее, чем Jetson.
Полагаю, что причины либо в gpu моего Jetson не работает по какой-либо причине, либо установка opncv была неправильной
как проверить аппаратное и программное обеспечение ???
